(.9 to .13 n*m) do not over torque. 5. install leads of the dut into the the ms06 on the evaluation board. use #6 self-tapping screws to secure the evalua - tion board to the hs20 heatsink as shown in the assembly diagram (figure1). parts list part # description quantity hs20 heatsink 1 eval30 pc board 1 ms06 mating socket 1 tw07 thermal washer 1 package before you get started ? all apex ampli?ers should be handled using proper esd precautions. ? always use the heat sink and thermal washers included in this kit. ? always use adequate power supply bypassing. ? do not change connections while the circuit is powered. ? initially set all power supplies to the minimum operating levels allowed in the device data sheet. ? check for oscillations. equivalent schematic
